A » Excessive oil consumption in older engines can often be attributed to worn piston rings, valve seals, or gaskets. These components can degrade over time, leading to oil leaks or increased oil burning. Additionally, clogged PCV (Positive Crankcase Ventilation) systems can exacerbate the issue by failing to properly ventilate the engine, resulting in increased oil consumption. Regular maintenance and timely replacement of worn parts can help mitigate these problems.
